Catheter structure and method for locating tissue within a body organ and evaluating the delivered therapeutic means simultaneously with delivering the therapeutic means

摘要

A catheter structure for use with a visceral electromyogram (EVG) system is provided. The catheter structure has an elongate tube structure with a distal end and a proximal end. Three electrodes cooperate with the distal end of the tube structure and obtain signals related to myoelectric activity inside the abdominal organ to locate the target tissue including the main electrical generation pathway in the organ Configured and arranged. A treatment delivery structure that cooperates with the distal end of the tube structure and is separate from the electrode provides the treatment at the target tissue at the same time that the electrode obtains a signal at the target tissue; As a result, it is configured and arranged to allow the effectiveness of the treatment means to be monitored.
